Specification of Letters Patent. 1

Patented Oct. 6, 1908.

Application filed May 28, 1908. Serial No. 485,429.

To all whom it may concern: I

Be it known that I, Cass L. KENNIooTT,

Chicago Heights, in the county of Cook and 5 State ofIllinois, have invented anew anduseful Improvement in Water Purifying Apparatus, of which the following is a specification.

My invention relates to improvements in that feature of a water-purifying apparatus which serves for automatically proportionof the arrow; Fig. 3, a section. taken at the i 1ine 3 on Fig. 1 and viewed in the direction of the arrow;Fig. 4,2. section taken at the line 4. on Fig. 3 and viewed in the direction 'ofthe arrow; Fig. 5, an enlarged sectionalview showing my improved construction of adjustable solution-feeding cup; 6, av

perspective View of details for adjusting the tipping-box on its support; Fig. 7, a broken enlarged section taken at the line 7 on Fig.

, '4 and viewed ;in the direction of the arrow, and Fig. 8, an enlarged perspective view of one of the two similar shock-absorbing wings provided in the tipping-box.

In the precipitating tank 9 is shown the downtake-conduit 10 at the upper 'endof which is supported a bfasket-likc dist'ributer 11 having an imperforate bottom and opensides through which tojpermit the discharge into the tank; and the raw-water supplypipe 12 is represented rising through the tank and as extenfdedj horizontally to discharge at its depending nozzle above the ,center thereof, the extension containing a shut-off valve, indie ted at 13, connected.

with one endof aflever 14 near its fulcrum,-

the opposite end of the lever having adjust ably connected with ,it a depending rod 15 carrying on its lower/end, in the tank, a float for regulatin." a usual manner, the

discharge from t e pipe 12 by the level of, which is shown tobe a citizen of the United States, residing at.

, its. upper edge, to en adjustably secured on the rod, is adapted to engage a bracket 19 extending into the path provided-with an overflow at 17. A stop 18,

of the stop to prevent undue rise of the float.

On beams 20 supported. upon the circumferentially flanged open top of the tank9 is supported and fastened the vessel 21, shown of the preferred general semicylindrical chemical solution. the level of which is indicated at 24:, and a smaller compartment 25, forming the mixing chamber for the chemical and the raw\ water to be treated by it, thefront and rear walls of this chamber beshape, with a partition 22 dividing it into a larger compartment '23 for containing the .ing shown somewhat extended, at 26,-f0r the purposehereinafter explained. On the base of the compartment 25 and extending transversely thereof is fastened a bar 27 bent in a manner to present inclined shoulders at its ends forming the buffers 28 and 29 for limitingthe movements of the tipping-box hereinafter described. A rock-shaft 30 is -jour-- naled in suitable confining bearings cen-' trally on the upper ends of the vessel 21 and partition 22 and carries in the compartment 23 a stirrer 31 for the solution, that shown comprising arms depending from the shaft and connected at their lower ends by a per-- forated paddle-bar 32. The shaft also carries to extend from it at an "angle to each other rigid arms 33 and 33, each carrying on its free end a hingedcup 3 1 01 peculiar construction forming a feature of my invention.- The cup consists of. a tube 35 rigidly united with one of the members of the hinge 36 member is formed into a, stop 37 to abut against, the arm and limit the extent of turning of the cup in emptying itself; and a ubular extension 38 telescoping the'outer end of the tube 35 andadjustable therein for varying the capacity of the cup, a set-screw 39 being provided for fastening the extensionin adjusted position. On the side of the tube 35 adjacent to the partition 22 is provided an anti-friction guide-i oller 40 ,adapted to ride with the motion of ihe rock- ;shaft against. the surffaceof the partition jaflnd upon the horizontal flange 41 formed on .ble the cup to turn on ts hinge and discharge its contents into the inking-chamber 25. s

The tipping-box 4248 of the ordinary gen; feral construction, involving a scoop-like ref connecting it with its carrying arm, which 43 form filling-openings between their outer ends and the partition, while between their I inner ends and the opposite corresponding end of ,the partition extend the sections forming the bottom 47 provided at their outer ends with the similar discharge-openings 48. For'adjustably supporting the tipping-box on the rock-shaft means are pro vided shown in detail in Fig. 6. On each end of the box is riveted ,or otherwise fastened to the outer face thereof, a clip 49 havi-ng the ends bent to extend at right-angles to its body-portion and formed into alininglyperforated bearing-ears 50 for a screw 51; and from the bael of the clip extends a rib 50 to bear agains the base of the adjacent portion of the box-bottom 47 as a reinforcement. Between the ears 50 extends a sleeve; carrying a lateral bearing 54 through which the rock-shaft passes. these sleeves thus afiording the medium of support of the tipping-box on the shaft; and the screw 51 works in the sleeve. with 'its hearings in the ears 50, and carries nuts 52, as shown. for fastening the box in any position to which it may be adjusted by turning the screws in their hearings to raise or lower the box, to

the extent permissible by the slots 46, on the shaift30, thereby to decrease or increase the welght of water in the box for efi'ecting its tipping movement.

The principal feature of my improvemimt consists in means for taking up the shock of the encounter of the tipping-box with the arresting abutments. To this end I provide on the base of each compartment in the box a similar wing 55 hinged at one end to the compartment-bottom and bent to an angle at its opposite end to protrude through the respective discharge-opening 48, this bent section 55' being provided on its inner face, near the extremity thereof, with a shelf 55 formed of an angle-iron, on which is supported a, cushion 36, preferably composed of a section of rubber hose. An opening 57 is provided in the body'of the wing and is flanked by guides 58 for a slide-valve 59 affording means for varying thearea of the opening, to vary the resistance to the movement of the wing of the liquid in the box-- compartnlent.

soo,2se

open, raw water flows from the pipe 12 into the compartment of the box 42 then under the discharge-nozzle of the pipe. The weight of the water tips the box to cause it to discharge through the opening 48 of that compartment into the chamber 2:), and this movement of the tipping-box rocks the shaft 30 to raise one'of the cups 34 in the compartment 23 along the partition 22 to permit it, by turning upon its hinge upon reaching the flange 41, to discharge the solution, with which it became filled in the compartment 23,-into the chamber 25'to mix with the Water discharged therein from the tippingbox; This movement brings the other compartment of the box under the flow of raw water to tip it in the opposite direction for discharge of the water from that compartment and for emptying the contents of theother cup 34 into the mixing chamber; and these operations are continued, the mixture from the chamber 25 discharging through the opening in its bottom (Fig, 3) upon the distributer 11 fromRv'hich ittlows into the tank 9 for the usual purpose. As the tipping-box turns the wing 55 in the discharging compartment thereof it encounters, at its protruding end, an abutment 28 or 29 in its path (depending on the direction of turnihg) and the continued movement or the box cushions the Wing against the body of liquid in that compartment, thereby causing it to take-[up the shock of the encounter with the abutment and rendering the movement of the tipping-box practically noiseless,- besides saving Wear on the parts; and in the rise of the wing the cushion 56 thereon encounters the under side of the bottom 47 to prevent shock and noise by the encounter. The degree of resistance of the liquid in a tipping-box compartment to the wing therein may be regulated by enlarging or decreasing the area of the opening 57 in the latter by adjusting the valve 59. The extensions of the sides of the chamber 25 afford shields against splashing over of the water discharging from the tipping-box.

What I claim as new and desire to secure by Letters Patent is- 1 1. In a'water purifying apparatus, the combination of a mixingchamber provided with abutments, and a tipping-box containing compartments and supported in the path of the flow to said chamber of water to be treated and discharging into said'chamber, and movable wings supported in said compartments and extending to engage said abutments in the rocking motion of said box and cushion the impact against the liquid therein.

2. In a ivater-purifyin apparatus, the

combination of a mixing-c amber provided with abutments, and a tipping-box contain-. ing compartments and su ported in the path. of the flow to said cham er of water to be treated and discharging into said chamber, and Wings hinged in said compartments with bent protruding end-portions engaging said abutments in the rocking motion of said box, for the purpose set forth.
